Domesticating (6)
I believe the answer is:
taming
'domesticating' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for taming that I've seen before include "Subjugation" , "for domestication" , "Reducing an animal to a domestic state" , "Domesticating, mastering" , "Overcoming wildness" .)
